中文拼音 [yáocèzhèng]
遙測幀
英文
telemetry frame-
The code synchronization pulse brought from code synchrolock has the synchronization benchmark heart function in the demodulation processing. at the same time, it is the base of frame demodulation and datum processing
位同步器產生的位同步信號起著遙測解調處理「同步基準」的關鍵作用，是后續幀格式解調和數據處理的基礎。Then, it fully describes the set - up of the system, including a detailed introduction of the system of hardware platform, the data interface of the hard and software, the data structure, the relevant controlling order of system hardware, the switch of the work mode, and the communication between computer and servo
接著，介紹了跟蹤系統的系統設置，其中包括了對遙測系統的硬體平臺的概述，通過系統硬體與軟體的數據介面和數據幀格式對硬體進行工作狀態的設置，並且還講述了系統的工作模式的切換方式，以及信號處理機與伺服器的工作通信。Abstract : some problems about overall design of a small unmanned air vehicle telemetry system are presented in this paper. the construction and fundamental principle of the telemetry system is simply introduced. according to the telemetry task requirement, the key problems which should be solved at first are demonstrated mainly by system " s capacity design and channel design. the needed data transmission rate is carefully calculated with the telemetry parameter table provided by user and on this basis the frame structure is decided. the bit error rate in factual telemetry channel is grossly estimated in theory and a channel encoding scheme is provided to improve data transmission quality to meet with the requirement for extremely low bit error rate
文摘:論述了某型號無人機遙測系統中的容量和通道設計問題.文中對該遙測系統的組成和原理進行了介紹.結合具體的遙測任務需求，在容量設計中確定了數據傳輸率和使用的幀格式，在通道設計中，通過計算實際通道中的誤碼率，提出了相應的通道編碼方案以確保數據傳輸的低誤碼率要求
